Answer / nk
There is nothing like virtual constructors but we can have
virtual destructors so that the destructor of the correct
object is called.
Ex.
Base *bptr = new derived()
delete bptr; then the destructor of the derived objetc is
called when the base destructor is marked as virtual.
else destructore of base class is called and may lead to
memory leak if we have allocated any new memory.

Answer / syed abdul gaffur.
CONSTRUCTOR:
Constructors cannot be virtual. Declaring a constructor as a virtual function is a syntax error.
DISTRUCTOR :
If an object (with a non-virtual destructor) is destroyed explicitly by applying the delete operator to a base-class pointer to the object, the base-class destructor function (matching the pointer type) is called on the object
